Abstract
Provided is a pneumatic tire comprising an annular interior surface having a circumference, and an air flow feature. The annular interior surface is adapted for engagement with a wheel, defines an interior surface circumferential direction along the annular interior surface in the direction of the circumference, defines an interior surface meridinal direction tangent to the annular interior surface and perpendicular to the direction of the circumference, and defines an interior surface normal direction mutually perpendicular to both other directions. The air flow feature is engaged with the annular interior surface, adapted to direct a flow of inflation air into a non-circumferential direction, and comprises an air flow feature surface comprising a portion that extends in the interior surface normal direction and the interior surface meridinal direction, and either extends more than 2 millimeters in the interior surface normal direction, or extends in the interior surface circumferential direction.
